To all whom it may concern Be it known that I, WILLIAM F. KInsEL, Jr., acitizen of the United States, and a resident of Altoona, county ofBlair, Stateof Pennsylvania, have invented a certain new and usefulImprovement in Truck Connections for Locomotives'and Cars, of which thefollowing is aspecification. I v

This invention relates to railway rolling stock, and more particularlyto electric locoother types of rolling stock.

In designing large electric locomotives, to obtain maximum tractiveeffort within the restriction of maximum wheel weight on the rail, theresulting number of wheels necessitates an excessive cab length which inturn compelsthe use of a plurality of trucks.

One of the objects of this invention 1s to prQvidemeans for transferringthe strains directly through the truck frames and practically in ahorizontal plane passmg through the draft gear..

the necessary relative movements of the trucks in passing aroundcontinuous or -re- Another object is to provide-a connection between thetruckframes which will permit verse-curves or over crossings.

Anotherobject of ,the inventionis to provide a construction in which theends of the truck frames are in abuttingrelationand a structureconstituting a link between such ends is independently supported, forthe purpose oftransmitting rom one truck tothe other. .A further objectof the invention is to provide a connection between the trucks whichwill absorb the cab shocks arising from pulling strains starting andstopping the locomotive. A further object is to provide means forpositively securing thecab .to the truck frames so that it will notyield in a longitudinal direction, at the same time allowing freedom ofmovement vertically and transversely, the vertical movement being per--S mitted -bythe springs and the transverse movement being necessary inorder to permit-passagearound curves.

One form of the invention is illustrated in the accompanying drawings,in which,

Figure l is a plan view of a pair of the i trucks of a locomotiveembodying the invention; Fig. 2 is a side elevation thereof with the cabshown in position above the trucks;

F of the truckconnecting means; and Fig. 4

ig. 3 is an. enlarged elevation and section may be actuated in any thisposition of disalinement the bolsters is a vertical section, the righthalf being on the line aa and the left half being on the line bb of Fig.3.

Referring to the drawings,A, A, indicate generally the trucks of anelectric locomotive. Each of these trucks is provided with .drivingwheels 10 and the driving Wheels preferred manner and since this part ofthe locomotive does not affect the present invention, a descriptionthereof is believed to be unnecessary.

Thetruck A' is provided with the usual side frames 11 on which ispivotally supported thebody bolster 12 which carries one end'of the body13. The truck B is similarly provided with side frames 14 which carrythe bolster '15, the latter supporting the opposite end of the cab 13.The inner ends of the side frames 11 are connected by an end casting 16and the inner ends of the frames 1d are connected by a similar castingl7. As'shown in Fig-.1, the castings 16 and 17 are in abutting relationand the abutting surface 18 of the casting 16 is curved on the'arc of acircle about the center of the pivotal connection of the bolster 12. Theinner surface 19 of the casting 16 is also curved about this center andis thus concentrio with the surface 18. In a similar manner the surfaces20 and 21 of the end castn 17 pivot of the bolster 15. When thelocomotive is on a curve, as shown in Fig. 1, in which the trucks areindicated as on areverse curve,

the trucks are out of alinement v with thebody and in moving to and fromf they swivel, with respect to the body,

12 and 15. From Fig. 2 it will be evident that the end castings 16 and17 are substantially in line with the coupler 22 about the pivots ofatthe end of the locomotive and therefore the strains are transferred fromone truck frame directly to the other substantially in line with thedraft gear.

Secured'on the underside of the body 13 are cross beams 23 and'24 whichsupport longitudinal respectively. From Fig. 3

beams To the lower side of the beams 25 there are-secured brackets .26'and 27. The lower ends of the brackets '26- that the beams 25,.bracketsengage the inner surfaces 19 and 21 of the end cast-- 0 11 structureinclosing the end castings of the truck frames and forming a tensionmember.

;through which pulling strains are transmitted directly from onetruckframe to the ether; It will also be evident that thecurvinggoctithe-surfaces 18, 19, and 21 permits independent lateralmovement of the ends of the truck frames and that sufiicient clearanceis. provided between the beams 25 and.
